ProFTPD and jailing user's to their home directory.

Question

I am running ubuntu karmic with ProFTPD and I have uncommented following line:

# Use this to jail all users in their homes
 DefaultRoot                    ~

This kind of works (users are jailed to their home when defining server path), when the user connects to the ftp they are initially in / ... meaning the root which is not what I want, I want the user to start of in it's home directory. When I set server path: home/admin it actually goes to that directory and I can see all files but i can't go to any sub directories...

so. 1. how do I start of in ~ 2. how do I enter sub directories of ~

thanks.
